Abstract Scope |
The Synthetic rutile was prepared by aeration leaching process in a novel gas-liquid-solid reactor and compared with traditional reactor. The effects of aeration leaching on the phase transformation of reduced ilmenite were studied at a liquid-to-solid ratio of 4:1 by XRD, while the microstructure and composition of the reduced ilmenite were characterized by SEM and chemical analysis. The vigorous stirring helped break bubbles and was favorable to the reaction. There exists an optimum value of gas flow rate. Using this process, synthetic rutile containing 0.6% metallic iron and 82.11% titanium dioxide were obtained at 2% ammonium chloride with 1.5% hydrochloric acid and reaction time 1 hour. |
